Now Sauce Diddy -- who manages the Sauce Twinz (and was wearing the red backpack at the concert) -- tells us the guys feel terrible that it happened at their show ... and want to do everything in their power to make it right.

"Steve is good people," Sauce Diddy tells us ... "He's going to get his chain back. I'm going to make sure of it. One way or another."

Diddy is adamant the crook is NOT affiliated with the Sauce Twinz -- he's just a "random stupid ass" -- but says Steve didn't exactly do the best job of protecting himself that night.

"He must have been drunk. He was mumbling on the mic and bumping into people. At one point, one of my artists tried to get Steve to leave the stage."

When asked if cops were involved in the chain-hunt, Sauce Diddy told us ... "Nobody's calling the police. We're gonna find it. We're gonna get it back."

NBA legend Steve Francis was the victim of a violent chain snatching at a rap show in Houston this weekend ... and TMZ Sports has footage of the brazen attack.

The 38-year-old, 3-time NBA All-Star was onstage with the Sauce Twinz -- a Houston rap duo -- when someone crept up on the unsuspecting Francis and tried to rip his gold chain right off his neck.

Problem is ... the chain didn't pop -- and Francis was dragged down to the floor where the culprit continued to yank on the necklace while the discombobulated NBA star tried to figure out what was going on.

Sources tell us the guy ended up removing the chain from Francis and booked it.

We're also told police were NOT called to the scene.

As for the perp, no word on his ID -- or if he's connected to the Sauce Twinz.

We reached out to Francis and the Twinz for comment -- so far, no word back.

Ronda Rousey couldn't just BEAT male fighters ... but she'd easily be ranked in the Top 20 in her division if she was able to fight dudes ... so says UFC ring announcer Bruce Buffer.

To be fair, Buffer says he doesn't ever see the UFC signing off on a Ronda vs. Man fight ... but says, "Quite frankly I'm sure she would do very well against at least half the division she's in which is the bantamweight."

For the record, the men's bantamweight division (135) is comprised of guys like T.J. Dillashaw, Dominick Cruz and Urijah Faber.

Still, Buffer says Rousey is a friggin' beast ... and "the most dominant fighting athlete in the world."

Fun Fact -- it took Bruce more time to announce Ronda on her way into the fight at UFC 184 ... that it did for Rousey to actually beat Cat Zingano.

Nick Young might not be making "SportsCenter's" top plays anytime soon ... 'cause the Lakers star just threatened an ESPN anchor after the guy dissed his GF Iggy Azalea on the air.

For some reason, ESPN anchor Robert Flores fired a shot at Iggy during a segment called, "What Did We Learn?" ... saying:

"We learned that according to the Lakers' Nick Young a dolphin recently tried to kill him. So Nick while dolphins are trying to kill you, your girlfriend is trying to kill hip hop ... let's call it even, ok?"

Needless to say, Swaggy P was PISSED and tweeted to Flores to let him know he's got a problem:

"@RoFloESPN I'm pretty sure we going to run into each other soon."

Sounds like a threat. But Nick didn't stop there ...

"You job is to talk about sports not what me and my chick got going on," Young wrote ... adding, "so we got a problem."
